(5) Select [ALARM/DIAGN] ---> [MENU (MENU 5)] ---> [ABS SERVO MONITOR] in the CNC monitor on GOT. Scroll
the page to display the [ABS. POSITION SET] screen.
Check that the STOPPER is applied for the axis for which the absolute position zero point is to be initialized.
(Note) The type of absolute position zero point initialization set is decided by the machine and axes
specifications, although "stopper method" can be selected by setting "1" for "#2049 type Absolute
position detection method". Confirm whether the machine specifications allow "stopper method" before
changing the type.
(6) Set "1" to "#0 INIT. SET" of the axis for which the zero point is to be initialized.
(7) Set the parameter "#2 ZERO".
(8) Start the axis for which the zero point is to be initialized with JOG.
(Note) JOG can be started only in the "#2 Zero" sign direction (machine end stopper direction). (If the JOG start
direction is illegal, the message "ILLEGAL DIRECTION" will appear.)
